S2008VTP

Overview

The Littelfuse S2008VTP is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. This component belongs to the S-Series, characterized by its surface-mount package and high reliability. It functions by increasing resistance significantly when excessive current flows through it, thereby limiting the current to a safe level. Once the fault condition is removed and the device cools down, it returns to its low-resistance state, allowing normal operation to resume without manual replacement.

Feature Summary

• Provides automatic resettable overcurrent protection for sensitive electronic components
• Features a compact surface-mount design suitable for automated assembly processes
• Maintains stable performance across a wide range of operating temperatures
• Offers reliable circuit interruption during short-circuit or overload events

Applications

• Portable consumer electronics such as mobile phones and tablets
• Computer peripherals including USB hubs and external drives
• Automotive infotainment and control module circuits
• Industrial control systems requiring robust overcurrent protection

Procurement Notes

Verify the specific voltage and current ratings against your circuit requirements before procurement. Ensure the selected variant matches the required hold and trip currents for your application. Confirm the package type aligns with your PCB footprint specifications. Check for any RoHS compliance certifications if required by your manufacturing standards. Always refer to the official datasheet for detailed thermal derating curves and installation guidelines.

Selection Notes

Select this component based on the maximum operating voltage and continuous current needs of your circuit. Consider the ambient temperature range to ensure proper tripping characteristics. Evaluate the space constraints on the PCB to confirm the surface-mount package fits. Assess the response time requirements to ensure adequate protection speed. Verify compatibility with reflow soldering profiles used in your production line.

Part Context

This part is part of Littelfuse's broader portfolio of PPTC devices, which are widely used for secondary protection in various industries. The S-Series specifically targets applications where space is limited and resettable functionality is preferred over one-time fuses. These components complement other protection devices like TVS diodes and traditional fuses in comprehensive circuit protection strategies.

Replacement Considerations

When replacing this component, ensure the substitute has identical voltage and current ratings. Verify that the physical dimensions and terminal configuration match the original footprint. Confirm that the new part meets the same safety certifications and environmental standards. Check for equivalent thermal characteristics to maintain proper circuit protection behavior.
